Drainage and Ventilation on the Sashes

Nearly forgot, The drainage and ventilation for the space around the sealed units. This goes on the TS Meeting rail and BS Bottom rail.

First drill the holes, a little difficult on the BS Bottom rail as the stroke on my drill press isn't long enough. So I did it in two stages and added a packer for the second stage. Then router the groove in, this should allow any water that gets past the seals to find the hole and drain away.

Credit Dave - clamp a same height as the top of the rebate, use a low fence (to avoid the clamps )on the router table - easy, cheers Dave.
